          Issue ID: 14352
           Summary: SDC test0075.d fails under against DMD
           Product: D
           Version: unspecified
          Hardware: x86
                OS: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P1
         Component: DMD
          Assignee: nobody at puremagic.com
          Reporter: shammah.chancellor at gmail.com

This compiles and works properly under SDC.   However, when ran against DMD the
assertions fail.  It appears as if "goto case" is not working correctly in DMD
based on what I can see.


```test0075.d
//T compiles:yes
//T has-passed:yes
//T retval:0
//? desc:Test goto case multiple cases in case list.

int transmogrify(int input) {
    int output = 0;
    switch (input) {
        case 0, 1:
            if (input == 0)
                goto case;
            else
                output++;
            goto case;
        case 2:
            output += 5;
            goto case;
        case 3:
            output += 5;
            break;
        case 4, 5, 6:
            goto default;
        case 7:
        case 8:
            output += 20;
            break;
        default:
            return -1;
    }
    return output;
}

int main() {
    bool defaultRan = false;
    switch(0) {
        default:
            defaultRan = true;
            break;
        case 0:
            goto default;
    }
    assert(defaultRan);

    assert(transmogrify(0) == 10);
    assert(transmogrify(1) == 11);

    assert(transmogrify(2) == 10);
    assert(transmogrify(3) == 5);
    assert(transmogrify(7) == 20);
    assert(transmogrify(8) == 20);

    assert(transmogrify(4) == -1);
    assert(transmogrify(5) == -1);
    assert(transmogrify(6) == -1);
    assert(transmogrify(128) == -1);
    return 0;
}

```
